New Delhi: Concerned over China's move to build three more dams on Brahmaputra river in Tibet, India on Thursday asked it to ensure that the interests of downstream states are not harmed by any activities in upstream areas.

Maintaining that India "carefully monitors all developments on the Brahmaputra River", official spokesperson in the Ministry of External Affairs on Thursday said the government has conveyed its "views and concerns" to the Chinese authorities, including at the highest levels.

"As a lower riparian state with considerable established user rights to the waters of the river, India has conveyed its views and concerns to the Chinese authorities, including at the highest levels of the Government of the People's Republic of China. India urges China to ensure that the interests of downstream states are not harmed by any activities in upstream areas," he said.

Meanwhile, Defence Minister A.K. Antony said that the government was yet to get details of China's plan to construct upstream dams on the Brahmaputra river and will take a considered view on the move.

"We will take a considered view about that," Antony told reporters at a function here when asked about China's move to build three hydropower dams in the middle reaches of the river which originates in Tibet Autonomous Region and flows into India.

"We have not yet received the factual position. So, my reaction at the time would be premature. We will wait for the details,” the Union Minister added further.

A media report on Wednesday said that the Chinese State Council had approved three dams at Dagu, Jiacha and Jiexu on Brahmaputra under an energy development plan for 2015.

Brahmaputra river is known as Yarlung Zangbo in China.

Beijing's decision comes at a time when India-China relations have improved considerably in all areas of cooperation and the two countries held lengthy round of the bilateral exchanges during National Security Advisor, Shivshankar Menon's visit here with his Chinese counterpart Dai Bingguo.

Sharing of cross border river waters has figured in the discussions but apparently China has not informed India of its plans to build the dams.

India has been expressing its concerns on this issue during the bilateral meetings. It figured during the then External Affairs Minister, S M Krishna's visit in March last year.
